19-5 Program examples
An example of measurements using the IV-S30 and a Sharp PC (JW70H) (2-point search for positional
deviation measurement) is explained below, using data flow, a flowchart and a timing chart.
Note 1: The PC must be write enabled. A Mitsubishi or OMRON PC will operate in the same manner,
but use different PC register and relay addresses.
Note 2: If the PC has not been connected to the object type input (parallel) on the IV-S30, the object
type No. is set to 0. To set different types, first enter the object type numbers (parallel) using
the type input terminals on the IV-S30.
